Subject [jira] Updated: (HARMONY-2004) [DRLVM] IPF support in interpreter mode, 'Hello World' stage
Date Wed, 01 Nov 2006 14:01:17 GMT
     [ http://issues.apache.org/jira/browse/HARMONY-2004?page=all ]

Ivan Volosyuk updated HARMONY-2004:

    Attachment: h2004_2.diff

h2004_2.diff : Patch contains almost the same state for IPF and has no negative impact on
other architectures.

IPF state:
    Jitrino compilation disabled - number of compilation errors
    JVMTI break point : x86 specific code moved under if-defs. May be moved out to some platform
specific files later.
    A few outdated native helpers commented out.
    Stack overflow guard page doesn't work - commented out.
    Native stubs for java monitors commented out.
    IPF signals code synchronized with x86 version.
    and more..

>                 URL: http://issues.apache.org/jira/browse/HARMONY-2004
>             Project: Harmony
>          Issue Type: New Feature
>          Components: DRLVM
>         Environment: Linux/ia64
>            Reporter: Ivan Volosyuk
>         Attachments: h-2004.diff, h2004_2.diff
> This is initial attempt to restore existing IPF support in DRLVM.
> First patch contains dirty solution to make something work. VM starts up and can run
simple tests.
> No threading, no GC for now.
> Moreover, most of the features are commented out: JVMTI, jitrino, some of jitrino helpers,
x86 code emitter.
> It will not even compile on other architectures but IPF.
> The patch is here just for informative purposes.
> My plan is to revise step by step each piece of patch and make it work on all supported
> I will need a help from components owners to help me with complex places.
